To ALL WHOM IT MAY OONOERN:

Be it known that I, MORITZ KOPPE, of New Yorlr' city, 219 Second street, in thecounty and State ot'lNew` York, have invented a new and improved Injector for Insect Powder; and I hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make anduse the same, reference being had to the accompanying drawing, lin which- Figure 1 represents a verticaicentral section of 4this invention. Figure 2 is a horizontal section of the same. Similar letters indicate corresponding parts.

i This invention consists in a vessel, the lower part-of which forms the chamber' intendedtofreceive theinsect,`

powder. This chamber is covered up by an elastic diaphragrn, which is subjected to the action of a spring, and to that of a thumb-piece or button, in such a manner thatby depressing the thumb-piece the air in the powderchamber is compressed, and a portion of the powder is forced out through a suitable spout, and on releasing the 4tliuuib-p'iece, the elastic diaphragm is forced back by theaction of the spring to its original position, ready for a new operation. A

A represents avessiel, made of sheet metal or any other suitable material, round, orin any other desirable form or shape. The lower part of this vessel forms the powder-chamber, which is lled with insect powder through a hole in its bottom or side, said hole .being closed by a plug, a, or' in any other suitable manner. From the powder-chamber .extends a spout, b, which may be straight lor curved, and-cf any desirable length. 'lhe-` powder-chamber is separated from the upper part of the vessel A by a diaphragm, e, which is` m'rade of India rubber or other suitable elastic material, and which is rmly secured to the inner circnmference'of the ,vessel A, either by clamping its edge between the sheet metal, as shown in fig. I, or in any Othersuitable manner. Said diaphragm is subjected to the action of a spring, d, which has a tendency to force the same up, and to the action of a thumb-piece, e, whereby the diaphragm can be depressed. The thumb-piece extends up through the top'oi" the vessel A, and it is secured to the diaphragm by means of two metal disks,f, as shown in the drawing, or in any other suitable manner. i

, By'depressing the thumb-piece the air in the powder-chamber is compressed, and a portion of the powder is forced out through the spout b, and on releasing the thumb-piece the diaphragm is forced up `by the spring d,

and the air returns-to the-powdcr-chamber through the spout. By these means an injector for inscctpowder is' obtained which is very convenientv in its operation'. It can be readily operated with one hand, and the jet of powder can be conveniently directed to any spot or corner where it may be wanted.

What I claim as new, and desirc'to secure by Letters Patent, is-.

An injector for insect powder', composed of a vessel, A, with elastic diaphragm c, spout b, spring d, and

thumb-piece e, substantially as and for the purposes set forth.
